3pt leaking down.When hot and shut down will leak down in 1/2 hour.Replaced seal on piston,replaced operating valves for 3pt,and adjusted linkage as service manuel advises.Thinking it may be thermal relief valve.Is there a way to check it without all the special tools stated in service manuel.Anything else i can try or advice on this problem.All advice is very welcome. Thank you Lloyd

I think that 1/2 hour to have it down should not be an issue at all if your three point has a load on it.

Without load this is no hood. I agree with thermal valve. Does this change if speed of drop screw us tightened all the way?

I will check tomorrow and get back.

Tightened all the way,slowed drop while running but not while stopped.

Put new thermal relief in, seems to be good now.
